The best advice I received was from another "younger" quilter. She told me -
"It is the flaws that make your quilt handmade, precious and valuable. If people wanted 'perfect' they would buy one ready made."
I now look at my gift projects with a different eye comprehending that the recipient will treasure the time I spent and the love behind it. Makes a world of difference for me. I no longer need to be perfect, but strive for excellence at my ability level. Perfection is for those who want their quilts evaluated and judged in hopes to win a prize. I don't think I will ever be at that level and it doesn't bother me. I get so much joy out of creating and giving that my heart is full each time I wrap up a gift.
